Precautions Note the following precautions in order to use the inverter properly.
1. Arrange for the power source capacity to be between 1.5 to 500kVA the inverter'scapacity. An excessively high peak current may flow to the power input circuit, anddamage the converter section if the wiring length between the power source and theinverter is shorter than 100 m with a power source exceeding 500kVA, or the phase-advancing capacitor is switched on the power source side. In this case, provideindividual power factor-enhancing AC reactors that match the inverter's capacity onthe inverter input side.
2. Do not connect the phase-advancing capacitor to the output side of the inverter. Doingso could result in damage to the phase-advancing capacitor.
3. Do not provide a magnetic contactor between the inverter and motor. To turn themotor on/off, use the RUN switch on the control panel or the control input terminal.Avoid frequently turning the magnetic contactor, provided on the power source, onand off.
4. Operating the motor by the inverter could increase leakage current and trip the earthleakage breaker. In this case, use earth leakage breakers designed for high frequencyfor this system and other systems.
5. Take the following precautions if using a built-in electronic thermal relay contained inthe inverter:・Check the rated current of your 3-phase induction motor, and set the appropriate
electronic thermal value.・Use one motor for each inverter.
6. If operating the inverter with multiple motors connected in parallel, select an inverter ofa capacity that does not exceed the total rated current of the inverter. Whencalculating by total output of the motor, the inverter’s rated current may be exceeded,depending on the type of motor.
7. The total wiring length between inverter and motor should not exceed 30 meters. If thewiring is to be longer than this, you should provide a reactor, etc., between inverterand motor.
8. Install the inverter securely to avoid injuries in the case of an earthquake.
9. Before running the inverter following an earthquake, check installation of the inverterand motor and make sure they are safe to operate.

Use the same size of wire for GND terminal ( ) as the wire for main circuit.
(2) Relay selection
For relays used in control circuits such as the control input terminal, you should use asmall signal relay (min. guaranteed current of 1mA or less) in order to prevent poorcontact.
＜Examples＞ Matsushita Electric Works: DS type, NK type, HC typeOmron: G2A type
(3) Control circuit switch selection
If using a switch instead of a relay, use a switch for extremely small current in order toprevent poor contact.
＜Example＞ Nihon Kaiheiki: M-2012J-G
*1 Motor cable is used if the distance between inverter and motor is 20 meters or less. If more than 20 meters,
use a larger cable.

System Configuration and WiringPrecautions when wiringThe inner circuit is still energized with a high voltage after the input power is turned off. Donot touch the inverter for at least 5 minutes after turning off the power. Main circuit(1) The inverter will be damaged if you invert the connections of the power input terminal
and motor output terminal (U/L1, V/L2, W/L3). Absolutely do not invert connections.(2) Do not ground the main circuit terminal.(3) Do not short motor output terminals (U/L1, V/L2, W/L3) together.(4) The GND terminal (E) is the frame ground (FG) for the inverter.(5) Be sure to use insulated crimp terminals for connecting to the main circuit terminals.
Control circuit(1) Use the wires with the insulation removed, as shown below, to wire the control circuit.
If the exposed area is too long, there is the possibility of a short occurring with theadjacent wire. If it is too short, the wire could be pulled. Twist the bare wires whenwiring, so that they will not get loose.
(2) Use a wire which diameter is less than 0.9 mm when wiring using a bar terminal or singlewire. If it is larger than 0.9 mm, the screw thread may be damaged when tightened.
(3) Do not apply more than 24VDC, 50mA to the output terminals (O1, C1), or applyvoltage to terminal in reverse.
(4) Input terminal configuration is internally pulled up from approx. +12V by approx. 3.3kΩ.You can control by contact or by open collector output. Do not apply external voltage.
NPN logic PNP logic(5) Do not short the frequency setting power source terminal (5V) and ground for control
terminal (G).(6) To directly drive the relay by the output terminals (O1, C1), mount a flywheel diode (FD).
(7) Use shielded wires for the cable to be connected to the control circuit.

Operation FunctionInverters of this series provide the following operation functions. You can issuecommands using the switches on the operation panel or on the terminal block.
Operation function ExplanationNormal operation Operation function with acceleration/deceleration time setting.
You can set acceleration time and deceleration time individuallywithin the range of 0 to 3600 seconds. *1
JOG (Jogging)operation
Operation function with zero acceleration/deceleration time. This functionis useful for positioning.When the "operation mode" is set to JOG (jogging) mode, the JOG(jogging) operation becomes valid.When a forward or reverse operation command is given after making thecontrol terminals between "I3" and "G" short, it becomes available tochange to normal operation from JOG (jogging) operation.JOG (jogging) frequency can be set within the range of 0 to 30 Hz.However, please note that when it is too high, a trip caused by an over-current may occur.
Free-run stop This function trips the applied voltage to the motor, and sets the motor to afree-run.This is useful when braking mechanically. However, be very careful not totouch the output terminals of the motor (U, V, W) even if the motor is free-running, because you can receive a serious electric shock.
DC brake This brakes the motor by applying direct current to the motor when theinverter stops from the operating status. When a forward, reverse, or JOG(jogging) operation command is given while the DC brake is activated, theDC brake is stopped, and the specified operation is started.
Positioning DC brake If a stop command is given during normal operation, soft-stop and brakingare activated when output frequency reaches 3 Hz (can be changed by theparameter setting.)
If the setting frequency is set to zero, braking is activated when outputfrequency becomes 1 Hz or lower.
Braking strength (torque) and time can be set by the parameters.Sudden stop(all regions) DC brake
If a stop command is given during normal operation, braking is activatedimmediately without soft-stop.
Braking strength (torque) and time can be set by the parameters. Braking time will be twice the time of "positioning DC brake mode".
You can perform multi-speed operation shown on the next page by conducting"Short"/"Open" settings in frequency setting selection terminals for operation modes with 4-speed or higher. No. 0 speed frequency is selected and the setting by the parameter "setting frequency (0 speed)" or by the external frequency setting dial is possible when all ofthe terminals are set to "Open."(In " frequency command selection", select whether 0 speed frequency is set by theparameter setting or by the external setting.)
Explanation of input terminal function(1) Priority for the function of input terminals is as follows:
DC brake < Normal operation < Jogging operation < Free-run stop < External forced tripEx.) ① The inverter goes into the operation immediately when a run command is
given while the DC brake is activated.② Free-run stop is performed when a free-run stop command is given during
jogging operation.③ The operation does not start even if a run command is given while free-run
stop is performed.A stop command is activated if a contradicting command is given (for example,command of forward and reverse operations are given at the same time).
(2) The trip status can be released when forward and reverse operation commands areboth given while tripping. Release the trip after removing the causes of the trip.

Electronic thermalrelay operation
(Monitor) (Flashes)
Monitor display flashes when outputcurrent reaches the electronic thermalrelay level and the timer operates.
Electronic thermal relay trip.Be careful of the size of theload when using.
Prevents tripping when acceleration/deceleration time becomes too long inthe following situations:
・ DC voltage of the converterexceeds approx. 375V.
・ Motor current exceeds inverter’scurrent limit operation point.
Increase acceleration/deceleration time ordecrease inertia load.
Insufficient voltagewarning
Instantaneouspower failureprotection
If DC voltage of the converter dropsbelow approx. 170V, it is regarded as“instantaneous power failure,” andinverter output is shut off.*1 If it dropsbelow approx. 100V, the control circuitis reset. If voltage is restored by thetime the control circuit is reset,operation can be restartedautomatically.*2
Investigate the wiring andpower source information.
Reverse prevention*3
Selecting the reverse preventionfunction prevents reverse operation ifthe inverter receives a reverse signal.
Check if the reversecommand has been given.
③
Restart preventionwhen power isrestored *2
Prevents the inverter from restartingautomatically if already given the runcommand when power is turned,restored following power failure orreset.
After commanding theinverter to stop, command itto run again.

Protective FunctionClassifi-cation 5-digit LED display Description of protection Countermeasures, etc.
Over-current trip
Trips if inverter output currentexceeds the rated current approx.by 200%.
Possible causes include drop inpower source voltage, excessiveGD2 load, acceleration/deceleration time is set too short,load short, or grounding. Take theproper measures to determinethe cause.
Regenerative over-voltage trip
Trips if DC voltage of theconverter rises above approx.400V.
If it trips while the inverter isrunning, deceleration time couldbe too short. Try settingdeceleration time longer. If it tripswhen the power is turned on, theinductance of the power-boostingAC reactor provided on the inputside of the inverter may be toohigh. Select an AC reactor thatmatches the inverter capacity.
Over-voltage tripretry when power isturned on
If over-voltage trip occurs whenthe power is turned on becausethe inductance of the power-boosting AC reactor provided onthe input side of the inverter is toohigh, etc., is displayedand output is shut off.The trip is automatically resetwhen DC voltage of the converterdrops below approx. 400V,enabling normal operation.*1
The capacity of the power-boosting AC reactor provided onthe input side of the inverter maybe too large. Select a reactor thatmatches the inverter capacity.
Over-load trip(Electronic thermalrelay)
If motor current continues toexceed the electronic thermalrelay setting value, load isregarded as being to highcausing the function to trip.
Try reducing load, modifyingoperating pattern, or raisingcapacity of inverter.
④
ＣＰＵ error
